But that's what is already in ISO 4217. It benefits international
trade in an increasingly global environment, that people dealing with
currencies of all sorts can use such codes (and I'm not sure of the
exact code for Afghani currency unit in ISO 4217).

Nothing says ISO 4217 codes have to be in use in Afghanistan if
Afghanistan prefers a different solution as a national standard.
